392 JL Wrangler, 3.5" True Dual Rate Coils, Front
The True Dual Rate™ Coils are manufactured of hi-tensile chrome silicon steel alloy that surpasses the typical aftermarket coil springs in extended length, ride quality and long-lasting durability. These springs are made specifically for the 392 JL Wrangler.
Features Includes:- True Dual Rate Coils, Two Measurable Coil Rates
- One of the Longest Free Lengths in Industry
- Stays in Coil Buckets, even at Full Droop
- Superior Ride Quality
- Excellent On & Off Road Stability
- Consistent Ride Height
- Resists Sagging
- Allows for Unbeatable Articulation
- All Coil Pads Included
- Motor Specific Upper Isolators
- Lower Front Coil Isolator/Correction Pads
The front true dual rate coils come with MetalCloak's Front Lower Coil Correction Pads. This polymer isolator replaces the OEM plastic part and corrects the coil bow that may be caused when using the worn parts. Fits in factory location and is a quick upgrade to fine tune your Jeep.
MetalCloak Thermoset Elastomer upper Coil Isolator upgrade pads are designed to last and outperform factory parts. The pads are made specifically for MetalCloak True Dual Rate Coils and are model specific.
MetalCloak “components” have been proven safe with the FMVSS certificate of safety configured with 37inch tires, full body armor and suspension lift.
Note: True Dual Rate Coils have been engineered to perform best with Duroflex control arms and 6Pak or RockSport shocks.
Note: MetalCloak does not recommend powder coating your True Dual Rate coils. The baking process in powder coating can, in some cases, cause the metallurgical properties of the coils to be changed, resulting in the loss of the lift properties of the coils. As such, the process of powder coating the coils will void any warranty stated or implied in relation to the coils.
Note: We recommend you have a suspension specialist align your Jeep once a MetalCloak suspension is installed.

THE TECH
What are True Dual Rate Coils?
MetalCloak True Dual Rate™ Coils have one of the longest free length in the industry for greater articulation without sacrificing the OEM ride quality.
Without the advantage of the Dual Rate Design, the required Spring Rate would be too low and "squishy" -- just loading your Jeep up with supplies would affect ride height and quality.
True Dual Rate Coils Create A "Virtual" Bucket!
By effectively lowering the bucket on the coil, you get a much more stable ride that reduces the potential for buckling. (Learn More about True Dual Rate Coils)
